Create a queue
Last updated: 2020-03-04 10:37:05
Interface description
This API (CreateQueue) is used to create a new queue under a user account.
- Domain name requested by public network API:
https://cmq-queue-{$region}.api.qcloud.com - Domain name requested by private network API:
http://cmq-queue-{$region}.api.tencentyun.com
The above {$region} in the domain name needs to be replaced with a specific region : gz (Guangzhou), sh (Shanghai), bj (Beijing), shjr (Shanghai Finance), szjr (Shenzhen Finance), hk (Hong Kong, China), cd (Chengdu), ca (North America), usw (American West), sg (Singapore). The region value in the common parameters should be consistent with the region value of the domain name. If there is any inconsistency, the request will be sent to the region specified by the domain name region based on the region value of the domain name.
At any time (including during internal testing), if the public network downstream Traffic is generated by using a public network domain name, Traffic and cost will be charged. Therefore, it is strongly recommended that users of the service on Tencent Cloud use Private network Domain name, private network will not produce Traffic cost.
